Abstract: Steam-flaked technology originated in the United States, the initial application in ruminant production. Steam-flaked technology is a method of grain processing, which grain has been made into flake after a series of processing such as steam hardening and tempering, roller press rolling and cooling. By a variety of effect of physical and chemical in the process of processing, the digestibility of starch and other chemical composition was improved, the contact area of nutrients and digestive tract digestive juices was increased, and the digestive site was changed to a certain extend. Thus, it could increase the animal digestion and absorption rate of grain. As a consequence, the steam-flaked technology could improve feeding value of grain, increase the efficiency of animals used for grain and induce feed waste and environmental pollution. In the article, the technological process of steam-flaked, the influence of steam-flaked on grain nutrients and its application in livestock and poultry production have been reviewed.

Key words: steam-flaked; technological process; grains; livestock and poultry production
